Planning

Identify the type and height of your garage door. Survey

your garage area to see if any of the conditions below

apply to your installation. Additional materials may be

required. You may ﬁ nd it helpful to refer back to this page

and the accompanying illustrations as you proceed with

the installation of your opener.

Depending on your requirements, there are several

installation steps which may call for materials or hardware

not included in the carton.

• Installation Step 1 – Look at the wall or ceiling above

the garage door. The header bracket must be securely

fastened to structural supports.

• Installation Step 4 – Depending upon garage

construction, extension brackets or wood blocks may

be needed to install sensors.

• Installation Step 4 – Alternate ﬂ oor mounting of the

safety reversing sensor will require hardware not

provided.

• Installation Step 6 – Do you have a ﬁ nished ceiling in

your garage? If so, a support bracket and additional

fastening hardware may be required.

• Do you have an access door in addition to the garage

door? If not, Model 7702CB Emergency Key Release is

required. See Accessories page.

• Look at the garage door where it meets the ﬂ oor. Any

gap between the ﬂ oor and the bottom of the door must

not exceed 1/4" (6 mm). Otherwise, the safety reversal

system may not work properly. See Adjustment Step 3.

Floor or door should be repaired.

SECTIONAL DOOR INSTALLATIONS

• Do you have a steel, aluminum, ﬁ berglass or glass

panel door? If so, horizontal and vertical reinforce ment

is required (Installation Step 12).

• The opener should be installed above the center of the

door. If there is a torsion spring or center bearing plate

in the way of the header bracket, it may be installed

within 4 feet (1.2 m) to the left or right of the door

center. See Installation Steps 1 and 12.

Rail Brackets

INSTALLATION STEP 1

Determine the Header Bracket Location

Installation procedures vary according to garage door

types. Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline

of the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet

(1.22 m) of the left or right of the door center only if

a torsion spring or center bearing plate is in the way;

or you can attach it to the ceiling (see page 13) when

clearance is minimal. (It may be mounted on the

wall upside down if necessary, to gain approximately

1/2" (1 cm).)

If you need to install the header bracket on a 2x4

(on wall or ceiling), use lag screws (not provided)

to securely fasten the 2x4 to structural supports as

shown here and on page 13.

3. Open your door to the highest point of travel as shown.

Draw an inter secting horizontal line on the header wall

above the high point:

• 3" (7.5 cm) above the high point for sectional door

and one-piece door with track.

• 8" (20 cm) above the high point for one-piece door

without track.

This height will provide travel clearance for the top

edge of the door.

NOTE: If the total number of inches exceeds the height

available in your garage, use the maximum height

possible, or refer to page 13 for ceiling installation.

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to

structural support on header wall or ceiling,

otherwise garage door might not reverse when

required. DO NOT install header bracket over

drywall.

• Concrete anchors MUST be used if mounting

header bracket or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage

door, springs, cables, pulleys, brackets, or their

hardware, ALL of which are under EXTREME

tension.

• ALWAYS call a trained door systems technician if

garage door binds, sticks, or is out of balance. An

unbalanced garage door might not reverse when

required.

INSTALLATION STEP 4

Install The Protector System

The safety reversing sensor must be connected and

aligned correctly before the garage door opener will

move in the down direction.

IMPORTANT INFORMATION ABOUT

THE SAFETY REVERSING SENSOR

When properly connected and aligned, the sensor will

detect an obstacle in the path of its electronic beam. The

sending eye (with an amber indicator light) transmits an

invisible light beam to the receiving eye (with a green

indicator light). If an obstruction breaks the light beam

while the door is closing, the door will stop and reverse

to full open position, and the opener lights will ﬂ ash

10 times.

The units must be installed inside the garage so that the

sending and receiving eyes face each other across the

door, no more than 6" (15 cm) above the ﬂ oor. Either can

be installed on the left or right of the door as long as the

sun never shines directly into the receiving eye lens.

The mounting brackets are designed to clip onto the track

of sectional garage doors without additional hardware.

If it is necessary to mount the units on the wall, the

brackets must be securely fastened to a solid surface such

as the wall framing. Extension brackets (see accessories)

are available if needed. If installing in masonry

construction, add a piece of wood at each location to

avoid drilling extra holes in masonry if repositioning is

necessary.

The invisible light beam path must be unobstructed. No

part of the garage door (or door tracks, springs, hinges,

rollers or other hardware) may interrupt the beam while

the door is closing.

Be sure power is NOT connected to the garage door

opener BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a

closing garage door:

• Correctly connect and align the safety reversing

sensor. This required safety device MUST NOT be

disabled.

• Install the safety reversing sensor so beam is NO

HIGHER than 6" (15 cm) above garage ﬂ oor.

INSTALLING THE BRACKETS

Be sure power to the opener is disconnected. Install

and align the brackets so the sensors will face each other

across the garage door, with the beam no higher than 6"

(15 cm) above the ﬂ oor. They may be installed in one of

three ways, as follows.

Garage door track installation (preferred):

• Slip the curved arms over the rounded edge of each

door track, with the curved arms facing the door. Snap

into place against the side of the track. It should lie

ﬂ ush, with the lip hugging the back edge of the track,

as shown in Figure 1.

If your door track will not support the bracket securely,

wall installation is recommended.

Wall installation (Figure 2 & 3):

• Place the bracket against the wall with curved arms

facing the door. Be sure there is enough clearance for

the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket (See

Accessories) or wood blocks can be used.

• Use bracket mounting holes as a template to locate

and drill (2) 3/16" diameter pilot holes on the wall at

each side of the door, no higher than 6" (15 cm) above

the ﬂ oor.

• Attach brackets to wall with lag screws (Not provided).

• If using extension brackets or wood blocks, adjust

right and left assemblies to the same distance out from

the mounting surface. Make sure all door hardware

obstructions are cleared.

Floor installation (Figure 4):

• Use wood blocks or extension brackets (See

Accessories) to elevate sensor brackets so the lenses

will be no higher than 6" (15 cm) above the ﬂ oor.

• Carefully measure and place right and left assemblies

at the same distance out from the wall. Be sure all door

hardware obstructions are cleared.

• Fasten to the ﬂ oor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot

on each sensor. Use wing nuts to fasten sensors

to brackets, with lenses pointing toward each other

across the door. Be sure the lens is not obstructed by

a bracket extension. See Figure 5.

• Finger tighten the wing nuts.

Recommended Wire Routing

1. Using insulated staples, run the wires from both

sensors to the rail at the door header (see Figure 6).

2. Run the wires through wire clip at the top of the rails.

NOTE: If your access door is near the garage door, you

may choose to install the door control at this time and

run the door control wire along the rail with the sensor

wires. If you choose this option, follow instructions

1-3 on page 20.

A 2x4 on its side is convenient for setting an ideal

door-to-rail distance.

• Remove foam packaging.

• Raise the opener onto a stepladder. You will need help

at this point if the ladder is not tall enough.

• Open the door all the way and place a 2x4 on its side

on the top section of the door beneath the rail.

• The top of the door should be level with the top of the

motor unit. Do not position the opener more than 4"

(10 cm) above this point.

INSTALLATION STEP 6

Hang the Opener

Three representative installations are shown. Yours may

be different. Hanging brackets should be angled

(Figure 1) to provide rigid support. On ﬁ nished ceilings

(Figure 2 and Figure 3), attach a sturdy metal bracket

to structural supports before installing the opener. This

bracket and fastening hardware are not provided (see

accessories).

Existing brackets from a previous installation may be

fastened to the sides of the motor unit as in Figures 1, 2

and 3. Then continue with step 6 below.

1. Measure the distance from each side of the motor unit

to the structural support.

2. Cut both pieces of the hanging bracket to required

lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with

5/16"-18x1-7/8" lag screws.

5. Fasten the opener to the hanging brackets with

5/16"-18x7/8" hex bolts, lock washers and nuts.

6. Check to make sure the rail is centered over the door

(or in line with the header bracket if the bracket is not

centered above the door).

7. Remove the 2x4. Operate the door manually. If the door

hits the rail, raise the header bracket.

NOTE: DO NOT connect power to opener at this time.

To avoid possible SERIOUS INJURY from a falling

garage door opener, fasten it SECURELY to structural

supports of the garage. Concrete anchors MUST be

used if installing any brackets into masonry.

INSTALLATION STEP 7

Install the Door Control

Locate door control within sight of door at a minimum

height of 5 feet (1.5 m) where small children cannot

reach, and away from moving parts of door and door

hardware. The installation surface must be smooth and

ﬂ at. If installing into drywall (Figure 1), drill 5/32" holes

and use anchors provided. For pre-wired installations (as

in new home construction), it may be mounted to a single

gang box (Figure 2). NOTE: After installation, a green or

amber indicator light behind the cover will indicate proper

connection. If not lit, the Lock and Light features will not

function (reverse wires to correct).

1. Strip 7/16" (11 mm) of insulation from one end of bell

wire and connect to the two screw terminals on back of

door control by color: white wire to WHT and white/red

wire to the RED (Figure 3).

2. Remove cover by gently prying on a side corner near the

top of the cover with a small ﬂ at head screwdriver

(Figure 4). Fasten with 6ABx1-1/4" self-tapping screws

(drywall installation) or 6-32x1" machine screws (into

gang box) as follows:

• Drill and install bottom screw, allowing 1/8" (3 mm) to

protrude above wall surface.

• Position bottom of door control on screw head and

slide down to secure. Adjust screw for snug ﬁ t.

• Install top screw with care to avoid cracking plastic

housing. Do not overtighten.

• Insert bottom tabs and snap on cover.

NOTE: The push bar may stick if the door control is not

mounted on a smooth surface. If a click is not heard when

pressing the push bar, loosen the two mounting screws

or relocate the door control to a smoother surface.

3. (Standard installation only) Run bell wire up wall and

across ceiling to motor unit. Use insulated staples to

secure wire in several places. Do not pierce wire with a

staple, creating a short or open circuit. If your access

door is near the garage door, you may run this wire with

the Safety Reversing Sensor wires along the top of the

rail. See page 17.

4. Insert all wires through the opening on top of motor unit

above the terminal block on the back panel (Figure 4).

5. Strip 7/16" (11 mm) of insulation from each set of bell

wires. Connect bell wires to the quick-connect terminals

as follows: white to white and white/red to red; white to

white and white/black to grey (Figure 5).

NOTE: When connecting multiple door controls to the

opener, twist same color wires together. Insert wires into

quick-connect holes: white to white and red/white to red.

6. Use tacks or staples to permanently attach entrapment

warning label to wall near door control, and manual

release/safety reverse test label in a prominent location

on inside of garage door.

NOTE: DO NOT connect the power and operate the opener at

this time. The trolley will travel to the full open position but

will not return to the close position until the sensor beam is

connected and properly aligned.

To prevent possible SERIOUS INJURY or DEATH from

electrocution:

• Be sure power is NOT connected BEFORE installing

door control.

• Connect ONLY to 24 VOLT low voltage wires.

To prevent possible SERIOUS INJURY or DEATH from a

closing garage door:

• Install door control within sight of garage door, out

of reach of children at a minimum height of 5 feet

(1.52 m), and away from all moving parts of door.

• NEVER permit children to operate or play with door

control push buttons or remote control transmitters.

• Activate door ONLY when it can be seen clearly, is

properly adjusted, and there are no obstructions to

door travel.

• ALWAYS keep garage door in sight until completely

closed. NEVER permit anyone to cross path of

closing garage door.
